LIQUID-FUEL BURNER.

Application filed January 26, 1914.

To all whom it may concern:

Be it known that l, GEORGE E. Earn, a citizen of the United States, residing at Chanute, in the county of Neosho and State of Kansas, have invented a new and useful Liquid-Fuel Burner, of which the following is a specification.

The present invention relates to liquid fuel or hydro-carbon burners, and aims to provide a novel and improved apparatus of that character.

@ne of the objects of the present invention is to provide an apparatus of the character indicated, having novel means for vaporizing liquid fuel, especially liquid fuel of low grade, such as crude oil, and for storing a sutlicient quantity of the vapor or gas after the flames have been turned out, to enable the vaporization of the fuel to be readily continued when the apparatus is to be employed again.

Another object of the present invention is to provide novel burner elements for effectively supporting combustion, and for heating the generator or retort.

ft is also within the spirit of the present invention to provide a contrivance of the nature indicated, which will be comparatively simple, and inexpensive in construction, as well as being simple, convenient, serviceable, and e'tlicient in its use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the in vent-ion herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein Figure 1 is a perspective view of the apparatus, a portion of the supply pipe being broken away. Fig. 2 is a cross section of the apparatus.

In carrying out the present invention, there is provided an elongated pan 1, which is arranged. to be set within the fire box of a cook or heating stove, although it is to be understood, at the outsehthat the present apparatus may be employed in divers capacities. Secured longitudinally upon the bot Specification of Letters Patent.

Patented June 2, 1914:. serial No. 5514, 531.

tom. of the pan 1, is a gas or vapor pipe 2, which is preferably clamped to the bottom of the pan 1. by means of clamps or clips One end of the vapor pipe 2 is provided with a cap 4t, while the other end has an elbow 5 attached. thereto.

A plurality of series of "l -cOuplings 6 are interposed in the vapor pipe 2, and have their branches or arms projecting upwardly. Uutlct or discharge tubes 7, each has one of its ends engaged to the branch or arm of one coupling 6, and has the laterally hori-. zontally projecting portion 8 bent from the said end, and the upstanding or upright portion 9 bent from the lateral portion 8. The upper or free ends of the vapor discharge pipes 7 are reflex ed or recurved, at 10, to form discharge nozzles bent downwardly toward the lower or lateral portions 8 ofthe discharge tubes 7', and toward the vapor pipe 2. Tie nozzles or tips of the tubes 7 project toward the portions 8 of the said tubes, in order that the flames or jets issuing from the nozzles will impinge against the portions 8 and vapor pipe 2 to superheat the vapor or therein.

Disposed above the burner tubes or elements 7, is a horizontal elongated tank or compartment 11, which forms a generator or retort, a connecting pipe 12 having one end attached to the elbow 5 and having its other end attached to the bottom of the generator or retort 11 at one end thereof. The con necting pipe 153 is provided with a needle valve 13 for controlling the passage of va por therethrough from the generator to the vapor tube 2 and burner elements. Attached to the other end of the generator 11 is the liquid fuel supply or feed pipe 14 which extends to a suitable liquid fuel tank 15, which may be elevated to feed the fuel by gravity, or which may be provided. with a pump for feeding the fuel by air pressure. 'lhat end portion of the supply pipe 14 connected. to the retort or generator 11 is preferably supported by means of an upright or standard 16 carried by one end of the pan 1, and the said end portion of the supply pipe 14 is also equipped with a use dle valve 17 for regulating the flow of fuel into the generator. 1

it is to be noted that the nozzles are directed downwardly from below the genera tor and toward the vapor pipe 2 underlying the generator, so that the flames will. first strike the lower portions 8 of the burner elements and the vapor pipe 2, and will then rise to heat the generator or retort for vaporizing the liquid fuel. The bottom of the generator or tank 11 is preferably flat, while the top thereof is rounded or semi-circular, the generator 11 and burner elements being carried by the pan 1, in order to be readily supported within the fire box of a stove, or the like. The valve stems of the valves 13 and 17 may be extended so as to pass through the walls of the stove or other structure to which the apparatus is applied.

In operation, the valve 17 is first opened to admit the liquid fuel into the generator 11, and the generator is then primed to create sufficient vapor for supporting conibustion at the nozzles, to continue the vaporization of the fuel, a tention being called to the fact that the generator need not be primed, after the apparatus has once been employed, whenever the apparatus is again started in use. The vapor being admitted to the nozzle through the valve 13, which has been previouslyopened, will support the flames for heating the generator 11, and for heating the stove or other structure to which the apparatus is applied. The flames descending from the tips of the burners will impinge against the lower portions 8 of the burner tubes and the vapor pipe 2, for superheating the vapor, to increase the effective combustion of the vapor. The flames in playing downward, and then rising, will also assist in diffusing the heat to the various portions of the generator or retort, for most effectively vaporizing the liquid fuel.

To enable the present apparatus to be readily started after being shut 01?, the valves 13 and 17 being closed when the apparatus is in operation, will cut 05 the supply of liquid fuel to the generator, and

will out 01f the passage of vapor from the generator to the burners, and consequently, the generated vapor within the generator or tank 11 will be confined or stored therein, so that when the apparatus is to be started again, it is only necessary to open the valve 13, and to ignite the vapor issuing from the burners, and to then open the valve 1? to permit the liquid fuel to enter the generator from the supply tank 15, the operation continuing as above described.

Having thus described the invention, what is claimed as new is 1. In a liquid fuel burner, a retort, a vaper pipe disposed therebelow and having 7 one end connected thereto, and a series of discharge tubes connected to said pipe and having upstanding portions provided with recurved nozzles directed toward the lower portions of said tubes and said pipe.

2. In a liquid fuel burner, a pan, a vapor pipe mounted upon the bottom thereof, a generator disposed above the said pipe, a pipe connecting one end of the vapor pipe and the generator, a series of ET-couplings interposed in the vapor pipe belowthe generator, and a discharge tube for each coupling, having one end connected thereto, each discharge tube having a lateral portion bent from said end, an upstanding portion bent from the lateral portion, and a recurved nozzle bent from the upstanding portion and directed toward the lateral portion and the said pipe, below the generator.

In testimony that I claim the foregoing as my own, I iave hereto affixed my signature in the presence of two witnesses.
